Best pico projectors

Top pick: Aurzen ZIP Tri-Fold Portable Projector — it's the one that behaves like a true pico projector: DLP optics, folds flat to slip in a bag, and runs off its own battery, so it works on a wall, a tent or a ceiling without hunting for an outlet. Bluetooth and USB cover streaming sticks and speakers.

Who the others suit:

• Vamvo Mini Projector — best budget all-rounder for a bedroom or dorm; 1080p, Wi-Fi and Bluetooth, and owners rate it highly.
• HP MC475 Smart Mini Projector — if you want a sharper native 1080p picture and smart apps in a small body, at a mid price.
• ARTSEA Mini Projector — cheapest way to try a mini projector; fine for dim rooms and casual movie nights.
• Xgimi Elfin Flip 4K — step up for a proper living-room picture; bigger and pricier, less pocketable.

Skip the 4K laser models here if portability is the point — they're home projectors, not pico ones.
